About the HTTP Headers
The HTTP Headers tool fetches a URL and displays the full set of HTTP response headers along with the status code the server returns. Inspecting headers reveals caching policy, content type, the server software, cookies, compression, and redirect behavior. It is a fast way to debug CDN configuration, verify cache rules, or audit what a server discloses about itself.
How to use
- Enter the full URL you want to inspect, including https://.
- Click Fetch to send the request.
- Review the returned status code and every response header.
Frequently asked questions
- What can HTTP headers tell me?
- They reveal content type, caching directives, the server and CDN in use, set cookies, compression, and security policies, among other things.
- Does this run JavaScript on the page?
- No. It makes a single HTTP request and reports the raw response headers and status, without rendering the page.
- Why might I see a redirect status?
- If the server returns a 301 or 302, the URL points somewhere else. Use the Redirect Checker to follow the full chain.
